We tested the airflow through our prototype module, inside a cardboard tube with some 3D printed adapters, using a UNI-T UT363 BT wind speed sensor.

...
The diameter of the tube that the airspeed was measured through was 30mm. This method of determining airflow is commonly used in HVAC duct air flow measurements.
Area of circle = (30mm / 2)2 x pi = 706.86mm2
Volume of air through module = 706.86mm2 x 6.1m/s = 15.52 m3/h
Volume of air through module = 706.86mm2 x 3.8m/s = 9.67 m3/h
Volume of air through module fan duct = 706.86mm2 x 6.5m/s = 16.54 m3/h
Volume of air through module fan duct = 706.86mm2 x 10.6m/s = 26.97 m3/h
Results:
| Fan | Volume of air through module (m3/h) | Volume of air in free air (m3/h) |
|---|---|---|
| Noctua NF-F12 iPPC 3000 | 15.52 | 26.97 |
| Qualtek FAD1-12025CBMW12 | 9.67 | 16.54 |
